Angel Aqua Flat Ceramic Oxygen Diffuser

Flat fine-pore ceramic diffuser for high-pressure oxygen supply, shaped to minimise bubble coalescence for even distribution. Produces 100-400 micron bubbles at around 40% transfer efficiency at 1 metre depth. Three sizes delivering 2, 4 and 8 LPM, each with a 6 mm barb into a 1/4″ BSP female fitting.

Price range: $140.00 through $220.00 ex GST

Product Information

Key Features

  • Flat fine-pore ceramic diffuser for high-pressure oxygen — cylinders, bulk oxygen supply or high-pressure oxygen generators
  • Flat profile reduces bubble coalescence, giving more even oxygen distribution than round diffusers
  • Fine bubbles of 100–400 microns for a high gas-to-water surface area
  • Approximately 40% oxygen transfer efficiency at 1 metre water depth
  • 6 mm barb fitting that screws into a 1/4″ BSP female fitting for a secure connection
  • Suited to transport tanks, fish grading and harvesting, and emergency oxygen supply
  • Operating range 1 to 2.5 kg/cm² (14.2–35.5 PSI)
  • Sizing — divide your total oxygen flow by the per-diffuser flow rate below (2, 4 or 8 LPM) to get the number of diffusers required.

Frequently Asked Questions

How many diffusers do I need?
Divide your total oxygen flow in LPM by the per-diffuser rate – 2 LPM for the DY101CF-E, 4 LPM for the DY101CF-C or 8 LPM for the DY101CF-A – and round up.
What pressure is required to run it?
It operates between 1 and 2.5 kg/cm2 (14.2 to 35.5 PSI), so it needs a regulated high-pressure oxygen supply rather than a low-pressure blower.
Does it suit pure oxygen or air service?
It is built for pure oxygen from cylinders, bulk supply or a high-pressure oxygen generator; a standard air blower will not reach its working pressure.
Why choose the flat type over the cylinder type?
The flat profile minimises bubble coalescence, so oxygen is distributed more evenly across the diffuser face.
How does ceramic compare with a rubber membrane diffuser?
Ceramic gives far finer bubbles – 100 to 400 microns against 1 to 3 mm for a membrane disc – for better transfer, while membrane discs move much more air at low pressure.
How do I clean it?
Calcium scale and biofilm gradually block the ceramic pores; soak the diffuser in a dilute acid bath, then rinse thoroughly before returning it to service.
What oxygen transfer efficiency can I expect?
Approximately 40% at 1 metre water depth, with deeper water giving longer bubble contact time and better transfer.
